Hi Zucca,
That is surprise that you are the first one to ask how to use out GPIB interface with Matlab. Even we had not tried this before.
I did some real simple and quick test use S82357 with Agilent function generator 33220A under Matlab R2012b.
First of all, you need to install the instrument control toolbox of Matlab.
Press that tab, and connect S82357 (F82357 should be same). Right click GPIB icon and select scan for GPIB instrument.
Here you need to be very patient and it will take more than 1 minute
to get the right instrument information back. I first though S82357 might be
stuck here, but after change to Agilent 82357B, it act in the same way. We finally find out that Matlab send *IDN? command to each GPIB address from 0 to 31 and waiting for their
response until timeout.
After you get the instrument information, you can connect to that instrument, send command and read data back.
That part shows S82357/F82357 can be recognized by Matlab and the the basic communication works fine. You may start from this, and see if your own code runs on well. Let me know your test result and we will be more than happy to know more from you.

Awesome support, I will suggest this GPIB adapter to other EE guys.
Take care,
